Used in the manufacture of sand casting equipment. Its main function is to: fill sand, loose sand in the sand box; compaction sand, through compaction, compaction by vibration, shock pressure, injection pressure, different methods of making sand box loose molding sand, the sand in the transportation and pouring process have the necessary strength; from mold, using the same institutions will look from the firm after the sand out of

Molding machine first appeared in the mid nineteenth Century, early moulding machine is a simple manual compaction band model mechanism, then adopts the compressed air as the compaction by vibration and compaction sand dynamics. 1890 a jarring moulding machine, make the modeling efficiency and precision have been improved sand. Molding machine according to the compaction molding method can be divided into different compacting type, jolt, shock pressure, shoot squeeze molding machine and sand throwing machine.
